Three-cylinder or four-cylinder cars, you can consider these five-cylinder cars!
As emission standards and fuel consumption requirements become increasingly stringent, "test-ready products" small-displacement three-cylinder engines have become popular, and many brands such as Volkswagen, Ford, Honda, Chevrolet, Buick, and Lynk & Co have launched their products. Its main sales models are equipped with three-cylinder engines.
Jittery and noisy, weak acceleration in the rear section, and questionable durability have become the original sins for three-cylinder engines that are despised by the public. Many extremes even say: "Odd-cylinder engines are a joke!"
If you don’t know what you know, you will know it, and it will only increase your laughter. Once upon a time, odd-numbered cylinder engines also had their own moments of glory, even if they failed to remain in the hearts of the public.
In the early years, the inline five-cylinder engine won many fans with its advantages of abundant power, smoothness and quietness. Later, it gradually faded out of the public eye due to its large size and displacement tax. What other five-cylinder “gem” models are on the market? And look down.
The public’s prejudice against three-cylinder engines puts five-cylinder engines in the wrong position. Many people think that five-cylinder engines with an odd number of cylinders are juddery and noisy, and their power is not linear. In fact, this is not the case.
The traditional four-cylinder engine crankshaft rotates 720° to complete a working cycle, which is equivalent to doing one work when the crankshaft rotates 180° (720°÷4=180°), while the five-cylinder engine crankshaft rotates 144° (720°) °÷5?=144°) to complete one work, that is, the five-cylinder engine cylinder has a 36° overlap (180°-144°=36°) when doing work, and the overlapping vibration between the ignition and working cylinder can offset part of the noise and vibration.
This means that the greater the number of engine cylinders, the shorter the ignition gap time and the smoother the engine operation will naturally be (engine vibration mainly comes from ignition and work). Three people carrying a sedan chair are not as stable as four people, but five people are obviously more stable. Because the cylinders are arranged in parallel and the cylinder and crankshaft structures are simple, the in-line five-cylinder engine has the advantages of high stability, abundant low torque, and greater fuel efficiency than a V6 engine of the same displacement.
Back to products, there are only a handful of independent cars using five-cylinder engines, and the early JAC Ruifeng M3 is one of them. At that time, the Refine M3 used a 1.6L inline five-cylinder engine with a maximum output of 120Ps and 150N·m, which was considered sufficient for that era. Later, due to increasingly stringent emission regulations, the entire Refine M3 National VI model series adopted a 1.8L self-priming four-cylinder engine (codenamed LJ4A18Q6).
As a well-known pickup truck model in the North American market, the Ford Ranger’s mass base is not afraid of its big brother F-150. It is equipped with a rare 3.2T five-cylinder diesel engine in its class, which is even more talked about. This "wonderful" engine can burst out 200Ps, 470N·m, and ample torque to help it easily get out of trouble in outdoor environments.
The popularity of Ford Ranger in the North American market is enough to show that local consumers recognize the five-cylinder engine. Form is secondary and performance is king. Once again, it is proved that existence is reasonable, so please stop talking about odd-numbered cylinders.
Although Ranger is not equipped with Ford’s latest 2.0T EcoBlue diesel engine, the selective catalytic reduction function of this 3.2T five-cylinder engine can not only improve exhaust emissions, but also improve fuel efficiency by 9%. The Ranger's official fuel consumption is "only" 8.9L/100km, which is not easy compared to competing products that often "break ten".
Compared with the 3.0T V6 diesel engine equipped in competing products of the same level, this 3.2T five-cylinder engine has the advantages of small size, excellent lightweight and abundant torque. Since it is installed in Ranger, an off-road expert, the durability and reliability of this five-cylinder engine must not be much different.
Ford Group’s first use of five-cylinder engines dates back to 2010.
At that time, Ford built a limited edition hatchback based on the Focus RS - the Focus RS500. It was equipped with a 350Ps, 460N·m 2.5T five-cylinder engine, which was 15 and 4.5 times higher than the maximum horsepower and peak torque of the Focus RS respectively. , the vehicle accelerated from 0-100km/h in just 5.6 seconds, which was quite fast at the time.
The origin of the five-cylinder engine can be traced back to the 1970s. At that time, Mercedes-Benz urgently needed a high-end engine to make its flagship sedan more "calm" and to enhance the company's technical image. Due to limitations in body size and cabin layout, Mercedes-Benz commissioned a senior engineer to develop a five-cylinder engine. This engineer was Ferdinand Piech, who later became world-famous as the godfather of Volkswagen.
In less than half a year, Ferdinand Piech led his team to produce five five-cylinder engine samples. However, due to budget constraints and Mercedes-Benz not delegating power to Pi?ch, he was frustrated and accepted the olive branch offered by Audi. He officially took office in 1972 to help Audi enter the U.S. market and solve the problem of exhaust emissions of the classic Audi 100 model in the U.S. at that time. Controversy over emission standards.
It was at this time that Piech's five-cylinder engine solution found its way. In 1976, the Audi 100 was equipped with a five-cylinder engine for the first time. After the market response was gratifying, Piech then developed a 2.1T five-cylinder engine for use in the Audi S1 ??(Audi 100 rally car), with a power reserve of 598Ps and 590N·m. With Quattro full-time four-wheel drive, you can overcome obstacles and maneuver in the rally field.
When innovation became a classic, this five-cylinder engine was gradually introduced to the mass-produced car market, and high-power four-cylinder engines also began to be adopted by high-end models. It was not until 2009 that Audi injected the racing soul of the Audi S1 ??into the new generation TT RS and equipped it with a new 2.5T inline five-cylinder engine. Of course, Audi's high-energy small steel cannon RS3 is also a loyal fan of this "five-cylinder engine" and made its debut in 2011.
What is little known is that this 2.5T mixed injection five-cylinder engine not only draws on Audi’s rally experience that year, but also draws on some of Porsche’s advanced engine technology. It can burst out up to 400Ps and 480N·m. , with the support of the DQ500 seven-speed wet dual-clutch gearbox, the Audi RS3 accelerates from 0-100km/h in only 4.1 seconds, putting many supercars to shame. After years of hardening, its reliability is beyond doubt.
Back to the Audi TT? RS, it is also equipped with a 2.5T inline five-cylinder engine DQ500 dual-clutch gearbox. Under the same power parameters as the Audi RS3, the 0-100km/h acceleration time is only 3.7s, which is a full 0.4s faster than the latter. He is worthy of being the fastest seed player in MQB.
You must know that the 0.4s gap is difficult for high-performance cars to catch up with. The professor believes that this is inseparable from the low drag coefficient and excellent lightweight level of TT RS (a full 100kg lighter than RS3).
It is reported that this generation of TT RS may become the swan song, and news that the Audi TT will be discontinued is also endless. Although Audi has not officially announced the news, judging from the model sales and product terminal discounts, it is almost the same. If the Audi TT?RS is discontinued, it is estimated that the Audi RS3 will be left to stick to the five-cylinder performance car camp.
Looking deeper, the reason why TT? RS and RS3 do not use the outstanding performance 3.0T six-cylinder engine is most likely due to considerations of body size and lightweight. Just imagine, if a six-cylinder large-displacement engine is inserted into the cabin of a small sports car or compact car, the redundant space that can be arranged in the cabin will be severely compressed, and enhanced air intake, intercooling, water cooling and Reserve space for hanging and other components.
To talk about performance aside from lightweight is tantamount to being a hooligan. The TT? RS and RS3 built on the MQB transverse platform have the natural disadvantage of being "top heavy and light tail". If they insist on using large-displacement six-cylinder engines, the control advantages of front-wheel drive vehicles will be further amplified.
For this reason, the five-cylinder engine has become a compromise choice for the Audi RS department, and can also form an engine for competing four-cylinder performance cars such as the Mercedes-Benz A45, Mercedes-Benz CLA 45, new BMW M235i, and BMW X2 M35. The suppression of displacement and number of cylinders kills two birds with one stone.
From this point on, the fourth-generation Volkswagen Golf MK4 was also a loyal fan of five-cylinder engines. The 2.3L V5 self-priming engine with a maximum output of 170Ps drove this little steel cannon. With ease. The engine is also the first to be equipped with cylinder deactivation technology, which can switch to four-cylinder mode under special working conditions to find a tough balance between power performance and fuel economy.
Feelings cannot be eaten after all. In this era of "either three or four", the five-cylinder engine that is neither high nor low has become the smallest branch of internal combustion engines. But it is undeniable that five-cylinder engine models have left an indelible mark on the history of automobile development.
One day, when Chinese consumers no longer hear about "three-cylinder" and when the 2.5L four-cylinder engine can also become synonymous with "large displacement", I will be lucky enough to witness the ups and downs of the five-cylinder engine. How happy we are.
